To all whom it may concern:

Be it known that I, BENJAMIN F. Bra n, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Me chanical Movements, of which the following is a specification.

The invention relates to mechanical movements and is designed particularly for use with toys, although capable of use in other relations. It has for its primary object; the provision of an improved movement of simple cheap construction adapted to convert oscillatory movement as imparted to a rotatable element intocontinuous forward rotary movement. Certain embodiments of the invention are illustrated in the accompanying drawings, wherein; J a

Figure 1 is a partial plan view and partial section through one embodiment of the invention; Fig. 2 is a front elevationof the bearing member which carries the main axle of the driving means; Fig. 3 is a front elevation of the apparatus when the driving member is in one position of lateralmovement; Fig. 4 is a view similar to that of Fig. 3 but with the driving member in its other position of lateral movement; Figs. 5 and 6 are front elevations of modified constructions Fig. 7 is a view slmilar to that of Fig. 1 of another modification; and Fig. 8 is a diagrammatic front view illustrating still another modification. I

The particular embodiment of the 1nvention as shown inFigs. 1 to 4 is designed for use in connection with a toy having a marble operating means adapted to discharge marbles to a basket or container carried by one endof a cordwhich passes'overthedriving wheel, such cord having a counterweight at its other end. The marbles are; intermittently discharged into the basket, causing it to move down after which thereisan automatic dischargeand the counterweight returns the basket to its original position. This back and forth movement of the. cord gives the driving wheel an intermittent 0scillatory movement, and the mechanism as illustrated constitutes the means for converting this oscillatory movement into a continuous forward movement, suchcontinuous forward movement being imparted to a "wind mill or other device, such as indicated Specification of Letters Patent.

Patented Dec.3, ieia.

Application filed January 11, 1918. Serial No. 211,342. t v a Figs. 1 to 4, the reference numeral 1 indicates the driving wheel over which passes the cord 2 carrying at one end thereceiving basket orreceptacle and at the other end the counterweight 3. This driving wheel is carried'by an axle 4 mounted with a loose run ning fitatits rear endjinthe upstanding bearingmember 5 and at its front end in the 6 being shown in front elei at ion Fig. A slot 7 1S p10Vld 6Cl 1n the bearlng member 6 so that the aXle and the driving wheel carrled thereby may move laterally a limited distance. Thebearing members 5 and 6 in the construction shown, which is relatively upstanding bearing member 6, suchmember lightand cheap, constitute integral parts of i the sheet metal member 8 which is secured in a any suitable manner to the base 9.

"The driving wheel 1 is preferably also made of sheet metal andis provided with the forwardly projecting annular flange 10.

Mounted inside this fl angge 10 are the intermeshing gears 11 and 12 which may also be madeof sheet metal stamped to the shape as indicated inFigsl and 3. These gears 11 and 12 are carried by the axles 13 and 1 1 (preferably made o fsheet metal and secured to the base in theisame manner as the mem her 8; The axle 13carries the wind mill A. or other device .whichit is desired to rotate forward continuously.

The flange 10 of the driving wheel congearsll and12,andis of such diameter,as indicated in Fig. 3, that when is in engagementfwith one of thefgears, such as 11,

it isputofengagement with the other gear mounted in the bearing members 15 and 16 v stitutes a frictional driving means for the 12. "Fig. 3 illustrates the position? of the parts when the counterweight 3 is moving down, thus rotating the driving wheel 1 in a-clockwise direction. At this time the flangqlo gages the periphery of the gear 11 and is out of engagement with the gear 12. This rotates the gear 11 and the wind mill A inaj clockwise direction. The posi- 1 tion' of the wheel] 1 is due to the mounting at A in dot and-dash lines. It willybe unof theaxle 4 the bearing slot 7 so thatas 119 the wheel 1 rotates in a clockwise direction the axle rolls to the right-hand endof the slot 7.

If the direction of movement of the cord is new reversed and the basket moves down pulling the counterweight up, the wheel 1 is rotated in a counter-clockwise direction, the parts assuming the position shown in Fig. 4:. At this time the flange 10 of the driving wheel engages the periphery of the gear 12 driving it in a counter-clockwise direction. This causes a movement in a clockwise direction of the gear 11 which is now out of engagement with the flange 10. In this case the axle l rolls to the left-hand end of the slot 7 (Fig. 2) carrying the'wheel 1 to the left. It will therefore be seen that regardless of the direction. of rotation of the wheel 1, the gear 11 and its shaft13 are always rotated in a clockwise direction so that the wind mill or other driven device continues its forward movement when the counter-weight is coming. up as well as when it is going down and there is a substantially continuous drive since the period in which the driving wheel 1 is being shifted laterally is comparatively slight.

Fig. 5 illustrates a modification in which the driving wheel 17, which is operated from the cable 18 is provided with a flange having the internal teeth. 19. A pair of intermeshing gears 20 and 21 are employed andv the construction is in other respects similar to that of Fig. 1, with the exception of the gear teeth 19, which serve to make the drive more positive than is the case in the apparatus of Fig. 1, where the driving engagement between the flange andthe gears is frictional- Fig. 6 illustrates another modification wherein the driven gears 22 and 23 are external with respect to the drive wheel 24 instead of being internal. The wheel 24 is driven by the cable 25 and is mounted as in the construction of Fig. 1, so that alimited lateral movement is possible. The, wheel is provided with a driving gear 26 adapted to engage frictionallyeither the gear 22 or the gear 23. The gears 22 and 23 are shown as being in frictionalengagement with each other. It will be seen that the gear 22 is always driven in the same direction regardless of the direction of movement of the wheel 21, such wheel shifting. backward and forward depending upon the direction of movement of thecable- Fig. 7 illustrates still another modification in which the driving wheel 27 is pro vided with an annular flange 28 adapted to frictionally engage a gear 29-. The wheel 27 is mounted upon an axle 30 which axle is carried int-he two bearing members 31 and. 32, the first of which is slotted as indicated at 33 in order to permit the axle and driving wheel to move laterally. The gear 29 is mounted upon a shaft 3i carried in the bearing members 31 and 32, such shaft being provided with the paddle wheel or other member which it is desired to drive. As the drive wheel 27 rotates in one direction its axle will roll in the bearing 33, to the position shown so that its flange 28 engages the gear 29, thus causing a forward rotation of the paddle wheel B. On the reverse movement of the wheel 27 the axle 30 will roll to the left-hand end of the slot 33 thus carrying the flange 28 out of engagement with the gear 29 so that the paddle wheel 13 continues to rotate forwardly due to its momentum. The application of driving force is thus intermittent instead of sub stantially continuous as in the other eonstructions heretofore described, but the device is somewhat cheaper than that of Fig. 1 and is suflicient for the purpose in a toy since any slowing up of the driven part is hardly perceptible.

Fig. 8 illustrates still another modification in which 35 is the flanged driving wheel having integral therewith a forwardly projecting driving gear 36. 37 is the driven wheel corresponding to the wheel 11 in Fig. 1. Upon the movement of the wheel 35 in a clockwise direction the flange of the drive wheel is brought into engagement with the gear 36 driving it in a clockwise direction. When the movement of the wheel is reversed, the wheel shifts to the left carrying the gear 36 into engagement with the gear 37 and carrying the flange of the wheel out of engagement with the gear 37. Under these conditions the gear 37 will still be driven in a clockwise direction. The wheel 35 is of course mounted for lateral movement just as in the construction of Fig. 1. Other modifications of the invention might be made without departing from the broad principle thereof, which principle involves the mounting of the driving wheel so that it will roll laterally to make or break driving engagement with a rotary driven member depending upon its direction of rotation. It will also be understood that the invention applies equally well to an intermittent drive rotatable driven element adapted to be engaged by the driving element when such element is 111 one position of lateral movement and disengaged therefrom when the drlvmg v in the bearing being automaticunder the inelement is in its other position of lateral movement, whereby said driven element has continuous forward rotary movement.
